GameObject::GameObject()
{
    sprite = NULL;
    pos.x = 0; pos.y = 0;
    vel.x = 0; vel.y = 0;

}

GameObject::~GameObject()
{
    if ( sprite != NULL )
        SDL_FreeSurface( sprite );
}   

void GameObject::LoadImage(std::string filename)
{
    sprite = IMG_Load( filename.c_str() );
    //clip.x = 0;
    //clip.y = 0;
    clip.w = sprite->w;           //It breaks here 
    clip.h = sprite->h;          // and here
